This invention relates to improvements in which the bolt of the latch emerges The locks. I striker plate 16 coacts with the latch to hold My lnventlon 1s particularly adapted for the door closed. Forautomobile use, an inidoor locks of automobiles. tial holding recess 16a and a full closure recess i U A primal feature of my invention is the 16?) are preferably provided.

mounting of the knob of the lock to. actuate The essentials of the lock proper include the latch bolt from its closed to its open posia spindle 17 having at its front end a"suit tion by pressure on the knob in the direction able form of handle 18 which may be secured of the desired movement of the door. That in position to the front end of the spindle I 10 is to say, when the occupant of the automobile by ineans of a positioning screw. The indesires to eXit from the automobile, the inner ner end, 17?) of the spindle "17 preferably handle of the lock is pushed in the outward extends through the inner side of the door and directionof the swing of the door, to thereby the inner handle 19 is secured thereto by its move the latch bolt from closed to open posipositioning'screw 20.

39 of my invention comprises acase, a latch bolt To attain the desired automatic closing of movable in thecase, a spindle for the handle e (1001" latch b and the movement of the mounted foraxial displacement, handle parts latch ol from Closed to open position by for the opposite sides of th d or s c r d displacement of the-handle and its spindle to the spindle and members associated with axially in the direction of outward swing of the latch belt at the handle s indl for a 'the door, I provide a member 23 controlling tomatically holding the latch bolt in its closed elatch b lfi ving an inclined face 24: C0- position and for moving the latch bolt from p r t ng: With an inclined face 25 Controlled closed to open position upon axialdisplacey t e spindle of the handle. ment of the handle parts in the direction of The 3 0 he in the form f a the desired opening of the door. block initially secured by a screw, clamp or so Further features and objects of my inventhe like to the shank 26 of the latch bolt, or tion are more fully described in'the accommay be cast integrally therewith. panying drawings, in which 7 r I Suitable means is provided for holding the 7 Fig.1 is a detail horizontal cross section bolt 15 in its closed position; such holding of an automobile door and associated body means is preferably resilient as in the form of parts provided with a latch or look embodya pair of expansive springs 27 having its one ing my invention; Fig. 2 is a sectional eleva end 27a lodged about a lug 28 on the inner tion on line 2-2 of Fig. 1; Fig. 3 is a front eleface of the casing 11 and its opposite end 276 vation of the same; and Fi lis a sectional lodged abouta lug 29 on the shank 26 or mem- 49 elevation on line 4-4 of Fig. 2, and Fig. 5 her 23. V p I is a detail elevation of the inner handle. Suitable means is also provided for guiding Referring to the drawings, the door of the or maintaining the shank 26 in its reciproautomobile is shown in outer view in Fig. 3; catorymovement to and from its closed posithe front face of the door is indicated by 10. tion; such means is most simple and effective The lock proper comprises a casing 11 which in the form of an expansive spring 30 having is suitably positioned between the door front its one end 30a lodged about a lug 31 on the 10 and the rear 12 of the door. The casing member 23 and its opposite end 301) lodged may conveniently include a face plate 13 exabout a lug 32 on the casing 11. tending the full thickness of the face of the Preferably, the shank 26 of the spindle is 50 door, and having an opening 1 L through in the form of a plate which is centrally slotted as indicated at 26a, see Figs. 2 and at, to receive and retain the handle spindle 17.

It will be observed that when the passenger desires to enter the automobile, he grasps the outer handle part 18 and pulls the same in the direction of the arrow 33, see Fig. 1, whereby the spindle 17 is acti ated in the direction of the arrow 34, i. e., axially of the spindle 17 and thereby forcing the inclined face 25 of the enlargement of the spindle 17 into contact with the inclined face 24 of the member 23 controlling the shank 26 of the latch bolt 15, and wherebythe shank 26 and the latch bolt 15 are moved in the direction of the arrow 35, see Fig. 1, counter to the springs 27 and compressing the same, until the latch bolt 15 has wholly emerged from a closure recess of the striker plate 16, whereupon the door swings outwardly on its hinges in the direction of the arrow Similarly, when the passenger desires to leave the automobile, the inner handle 19 is pushed in the direction of the arrow 34:, Fig. 1, and corresponding action of the lock parts takes place.

My invention is also advantageous in the stage of closing the door, in that by rasping the handle, either by pulling its outer handle 18 or by pushing the inner handle 19, in both instances the flat face 25a is brought into engagement with the contiguous portion of the inner fiat face 11a of the casing 11, thereby wholly freeing the stay bolt 15, its shank 26 and its controlling member 23 from engagement with the handleparts, and particularly the spindle 17, and rendering the manual force applied to the door wholly effective in moving the door to its closed position.

A key-lock 36 may be provided for locking the lock proper in its closed position; such key-lock 36 is preferably accessible from the exterior side of the door. The lr-ey lock 36 may eifect locking by engagement of its bolt 37 in the recess 38 of the spindle 17.

Preferably, as appears in Figs. 1, 1 and 5, the inner handle 19 is arranged as a plate flush with or countersunk relative to the inner face 12 of the door, so that the door may not he accidentally struck or engaged by the body of a passenger within the automobile. For such purpose, the inner escutcheon plate 22 is provided with an oval or other suitable opening 22a, having a correspondingly curved flange 226, for guiding the inner push plate 19. The contour of the inner push plate 19 may be designed to accommodate receiving the thumb or two fingers for applying pres sure for opening the door from the interior of the automobile body.

lVhile my invention is particularly adaptable for locks of automobile doors, it will be apparent that the invention is applicable for general use in doors.

Whereas I have described my invention by reference to specific forms thereof, it will member on the interior understood that many changes'and modifications may be made without departing from the spirit of the invention.

I claim 1. The combination of a door for an enclosure, means for mounting said door to open in a direction outwardly of said enclosure, said door being provided with recesses respectively on its inner and outer faces, a latch bolt carried by said door, means having an inclined face controlling said latch bolt, spring means biasing said latch bolt to ward its locking position, a handle for the outer face of thedoor constructed to be pulled manually, a member adapted to be pushed manually at the inner face of the door and wholly disposed within said recess on the inner face of said door, a spindle unitarily con necting at its outerend said handle through said recess on the outer face of the door and said push member at its inner end, and means operated by said spindle for operating said inclined faced means, whereby said latch bolt i moved to open position against its said spring biasing means by manually pulling said handle on the exterior of the door and by manually pushing said push member on the interior of the door.

2. The combination of a door for an enclosure, means for mounting said door to open in a direction outwardly of said enclosure, said door being provided with recesses respectively on its inner and outer faces, a latch bolt carried by said door, means having an inclined face controlling said latch bolt, spring means biasing said latch bolt toward its locking position, a handle for the outer face of the door constructed to. be pulled manually, a member adapted to be pushed manually at the inner face of the door and wholly disposed within said recess .on the inner face of said door, a spindle unitarily connecting at its outer end said handle through said recess on the outer face of the door and said push member .at its inner end, and inclined means operated by said spindle for operating said inclined faced means, whereby said latch bolt is moved to open position against its said spring biasing means by manually pulling said handle on the exterior of the door and by manually pushing said push of the door. In testimony whereof I have signed this specification this 21st day of Nov., 1928.
